2.7" cistern flush

[carlywarly]

We are trying to replace the push button flush on our toilet. We've got a replacement flush, that includes seals for 1.5" and 2" cisterns, however the diameter of the hole at the bottom of our cistern is bigger, about 2.65cm/2.7". We've attempted to use the 2"seal,with the old doughnut seal, and it's got a small leak. So my question is will a new doughnut seal solve the issue, or is there such a thing as a replacement flush for a larger hole? Help please!

In the cistern or in the toilet pan / base ?

The hole in the bottom of the cistern

Never seen one that big before you might have to change the cistern / whole toilet

Have you tried two washers either side ?

Is the leak because of using the old donut washer, if so, can you obtain a new one? If it’s because of the valve outlet size the perhaps email/contact Parts for Toilet,Float Valves,Toilet Spares uk,spare parts cistern,Toilet spare parts,Toilet parts, diaphragms, flushing valves - toiletspares.co.uk - https://www.toiletspares.co.uk/.
